Troyanec [42]

Answer:

$z= \frac{pd-59}{-2+p}$

Step-by-step explanation:

-p(d+z)=-2z+59

-pd-pz=-2z+59

lets bring all z integers on one side

-2z+pz = -pd-59

z(-2+p)=-pd-59

z = (pd-59) / (-2+p)

The nature center has a fish tank

ANEK [815]

Answer:

288 small fish.

Step-by-step explanation:

The first thing is to calculate the volume of the prism, which would be the area of the base (length by width) and that by the height, that is:

a = l * w * h

l = 6

w = 4

h = 4

Replacing

a = 6 * 4 * 4

a = 96 cubic feet

they tell us that per cubic foot there is room for 3 small fish, therefore:

96 * 3 = 288

Which means that there are 288 small fish.
